Maternal vascular lesions were more common in the PIH group and combined group (61% and 59%, respectively), compared with the FGR group (16.2%; P < .001), and villous lesions were more common in the combined group, compared with the FGR and PIH groups (79.5%, 53.5%, and 46.9%, respectively; P = .004). Fetal villous changes were observed in 16.2% in the FGR group, compared with 3.1% in the PIH group (P = .03), and chronic villitis was 15.2% in the FGR group vs 1.6% in the PIH group (P = .004).

So this isn't really something they can use for diagnosis, but after the fact. When they check the placenta in pathology, PE placentas turn out to be broken in a different way from IUGR placentas. The damaged areas are damaged in a different way. (I quoted the statistics bit because the p-values are pretty sweet -- this is definitely statistically significant.)
